Sorry, I completely missed the PowerBook reference.
Still much the same answer, except that Panther (OS X 10.3.x) is not supported. Maximum is 10.2.8. - and 32MB RAM just isn't enough!, And, the 2GB hard drive isn't a good choice for working with OS X.
If you get those upgraded, then Panther _is_ possible through XPostFacto
